Speedrun Royale

I want level editor in the game

Pls make the game be available to be played offline as well, as to practice speedrunning each arena without having to race with an opponent. Also, fix the high jumping, since sometimes I cant reach at higher platforms when holding jump and sometimes I can, so is killing each enemy by jumping like it was Mario, since I sometimes get hit by an enemy whenever I do that instead of just killing the enemy.
